I am new here, I hope this is the right place to ask the following.
I am practicing Étude 2 by Philip Glass and there are some parts of the score that look impossible for the fingers. But I see sometimes a different notation.
For example here you see in red that he used the caret and “smaller” notes but if you try this in the piano is impossible to play all at the same time. If I listen to the piece I am almost sure I only hear the higher notes in the right hand.
What is this notation telling me exactly?
